Latest Excalibur desktop installer forces LXQt?

devuan_excalibur_6.0.0_amd64_desktop.iso dated 02-Nov-2025 left me with an LXQt desktop and not XFCE as I wanted. I thought I must have made a mistake so ran the installer again, very carefully making sure that only XFCE was selected - and ended up with LXQt again. This seems to be a bug in the installer?

Re: Latest Excalibur desktop installer forces LXQt?

Hello:

... a bug in the installer?

Hmm ...
You may want to consider the possibility of the Excalibur installer becoming self-aware.
And as a result, defending itself from XFCE.

Just taking the piss ...

Best,

A.

Hmm... I got Xfce here.  If you don't mind going through the installer (again!), at the end when it prompts to reboot, hit Alt-F2, then <Enter> to come to a prompt.  type

cp /var/log/syslog /target

then Alt-F1 back to the installer and select <continue> to reboot.  I'd be interested in seeing a copy of your /syslog file to hopefully find out what went wrong.

Re: Latest Excalibur desktop installer forces LXQt?

The installer USB stick doesn't seem to be mounted as root during the installation; I copied the syslog there but it wasn't on the stick afterwards (RAM-disk?). I don't have any other USB sticks to hand. /mnt and /media were both empty and lsblk isn't present during the installation phase, so I couldn't see what drives were available to mount. Now I've rebooted after completing the installation A THIRD TIME and I still ended up with LXQt. I have a photo showing the relevant menu in the installer, and my selected options, but since it's no longer possible to post images on the Internet you'll just have to imagine what it looks like.

Don't get me started.

Re: Latest Excalibur desktop installer forces LXQt?

Being a stubborn ******* I went through the installation a fourth time, this time mounting the NVMe and copying the syslog there, then I moved the USB stick to my main computer and reformatted it as EXT4, reinserted it in the new machine and copied the syslog onto the stick - so I've got it here for you now. But how do I share it? There's no attachment option in the forum.

Re: Latest Excalibur desktop installer forces LXQt?

Looks like it installs both LXQt and XFCE?

Re: Latest Excalibur desktop installer forces LXQt?

Yes it does... I'll try it out to see if I get the same. Will take a little while though.
Did you install with or without network?

Thanks. I used "Expert Install", without network.

Re: Latest Excalibur desktop installer forces LXQt?

Hm, here the default slim login puts me into an xfce session.  But there are several lxqt packages that got installed, including lxqt-session.  These can probably all be safely removed with apt remove lxqt*

I think, possibly, they got pulled in from network-manager-applet

aptitude why lxqt-session
i   task-xfce-desktop      Recommends network-manager-applet | connman-gtk | cmst
i A network-manager-applet Depends    policykit-1-gnome | polkit-1-auth-agent
i A lxqt-policykit         Provides   polkit-1-auth-agent
i A lxqt-policykit         Depends    lxqt-session

Re: Latest Excalibur desktop installer forces LXQt?

makes sense, if anything it should install the policykit-1-gnome as that does provide the polkit-1-auth-agent that would integrate the best with gtk and the network-manager-applet, however my guess is that apt resolved the dependencies getting a list of which packages provide polkit-1-auth and choose the first available option by alphabetical order, were the lxqt agent not available it would had gone with the mate agent...

edit: i just noticed that the policykit-1-gnome agent was removed in trixie because it is unmaintained upstream as stated here https://bugs.debian.org/cgi-bin/bugrepo … bug=990271

so the real solution is to install the mate-polkit-bin package as that WILL integrate with a mainly gtk environment without pulling the lxqt session NOR the mate-session package

Re: Latest Excalibur desktop installer forces LXQt?

mostly as a frame of reference with respect to an earlier post, this is from a stock daedalus install, xfce desktop:

devuan@devuan-pc:~$ aptitude why lxqt-session
i   task-xfce-desktop             Depends  slim | lightdm                                          
p   lightdm                       Depends  lightdm-gtk-greeter | lightdm-greeter                   
p   x2gothinclient-minidesktop    Provides lightdm-greeter                                         
p   x2gothinclient-minidesktop    Depends  mate-desktop-environment-core                           
p   mate-desktop-environment-core Depends  mate-notification-daemon (>= 1.26) | notification-daemon
p   cinnamon                      Provides notification-daemon                                     
p   cinnamon                      Depends  network-manager-gnome                                   
i A network-manager-gnome         Depends  policykit-1-gnome | polkit-1-auth-agent                 
p   lxqt-policykit                Provides polkit-1-auth-agent                                     
p   lxqt-policykit                Depends  lxqt-session

Re: Latest Excalibur desktop installer forces LXQt?

Hm, here the default slim login puts me into an xfce session.

And I'm always logged in to an LXQt session. Could this discrepancy perhaps have something to do with me installing on a Ryzen system with a Vega iGPU?

Re: Latest Excalibur desktop installer forces LXQt?

It was a bit unfortunate in the timings, that trixie was released with the old gnome polkit removed but the new xfce-polkit package left out by the freeze: https://tracker.debian.org/pkg/xfce-polkit

The xfce-polkit also seems quiet upstream...

Re: Latest Excalibur desktop installer forces LXQt?

My ceres seems OK for now but the test PC with excalibur, upgraded from daedalus today,  judged gnome polkit untrusted so it is disappeared now. Just installed polkit mate per recommendation.  Thanks a lot....

Re: Latest Excalibur desktop installer forces LXQt?

I'm always logged in to an LXQt session

On the slim login screen, press F1 to switch login session
it's safe to remove lxqt-session (which will in turn remove lxqt-policykit), because, curiously, the offline desktop installs both lxqt-policykit and mate-polkit

Re: Latest Excalibur desktop installer forces LXQt?

so there is a project that implements a command line policykit auth interface intended to build custom polkit agents with scripts.

https://github.com/OmarCastro/cmd-polkit

it has examples to use rofi and zenity as GUI frontend, so it should be possible to build an auth agent with any toolkit frontend we want, will check the project out in depth later, compile and give it a try.
